7. Entrenching tool/weapon

eBay.com

Why carry around a saw, a weapon and a shovel when you can simply use a U.S. Army-issue entrenching tool? You’ve seen soldiers with these folding shovels strapped to their backs, and come doomsday, you’ll need to add one of these to your arsenal. Made of durable steel, this item will help you dig holes and cut trees for shelter (it has a serrated edge), and because it’s heavy, you can swing it as a weapon if you need to.
